These converts knew the importance of standing together in unity. The people all agreed with their leader. Together they came forth “vouching and covenanting with God” that their repentance was indelible. They then began to work hard together with their hands. They changed from being idolatrous (24:18). They firmly accepted the truth both verbally and practically—they really applied the gospel to themselves. That is an important example for us when we repent and want to change. Change is usually not easy. We cannot expect to repent and not have to expend effort. Doing it together is best.
They associated with good people. They became friendly with the Nephites, and that would really have helped their repentance. If we continue running with the wrong crowd, that does not facilitate our progress either.
Stunningly, they all remained committed as a group. This appears to be an ordinance that was not conducted one by one; they were all willing as a group to pledge to honor this commitment together. There was strength in numbers here. Perhaps, in the repentance process, we can become stronger in overcoming problems as communities if we are all committed to the change.
They all buried their weapons. They found whatever the implement of the sin was, and buried it deep within the ground. Maybe we could look for a symbol of our repentance too. I do not know what your implements might be, but, if you struggle with the Word of Wisdom, you may consider confiscating whatever food or drug tempts you. Whatever it might be, bury it deep and get it out of your way.
They faced the challenges and oppositions together, whatever the costs. Many were killed rather than take up arms again. The result was horrific, but the effect was more powerful than anything else they could have done, and many of their attackers came over to their side.
